icon request: Incognito / Spy Icon (Default, Outline, Filled, Sharp)

### Describe the Icon

Hello Ionicons team 👋

I would like to request a new icon for an “Incognito / Spy” concept.

This icon would be useful for features like:

- Private browsing mode
- Stealth / invisible user mode
- Anonymous activity
- Spy / hidden tracking features (UI representation)

Suggested concept:
A face or figure with disguise elements (hat, glasses, mask, or hidden eyes), or a simplified “anonymous silhouette” style icon that represents privacy and invisibility.

Variants requested:

- Default
- Outline
- Filled
- Sharp

Use cases:

“Incognito mode” toggle in apps
Privacy settings
Hidden/stealth features in social or chat apps
Security tools dashboards
